I made a VM with the mac address
Code:
13:37:be:ef:ca:fe

Now I can't access the VM Web UI and I can't delete the VM with cli tool either

Does anyone know how to get rid of it? Thanks


Code:
user@tank:~$ cli
[tank] service vm delete 6
Error: libvirtError("XML error: expected unicast mac address, found multicast '13:37:be:ef:ca:fe'")

What's the output of midclt call vm.device.query | jq? Your NIC with the odd MAC should appear in this list. You may be able to fix it with midctl call vm.device.update <id of NIC> '{ "dtype": "NIC", "attributes": { "mac": "<corrected MAC>" }, "vm": 6 }'.

OK, now we have to break out the big guns to perform SQL-fu on the configuration database.
Code:
root@truenas:~# sqlite3 /data/freenas-v1.db

sqlite> DELETE FROM vm_device WHERE id=38;
sqlite> .exit


This should delete the bad NIC device. You're free at this point to create another NIC device for this VM, or delete the VM altogether.

Ok so that worked to remove the NIC from the VM but the web UI is still giving me the same error under Virtualization. Do I need to reboot or reload something?

when I go to the ui/vm page I get this error instantly without the rest of the page loading.

Code:
